(a) The practice of the healing arts shall not be construed to include any person administering epinephrine in emergency situations to a student or a member of a school staff if: (1) The person administering the epinephrine reasonably believes that the student or staff member is exhibiting the signs and symptoms of an anaphylactic reaction; (2) a physician has authorized, in writing, the school to maintain a stock supply of epinephrine; and (3) the epinephrine is administered at school, on school property or at a school-sponsored event.

(b) Any person who gratuitously and in good faith renders emergency care or treatment through the administration of epinephrine to a student or a member of a school staff at school, on school property or at a school-sponsored event shall not be held liable for any civil damages as a result of such care or administration or as a result of any act or failure to act in providing or arranging further medical treatment where the person acts as an ordinary reasonably prudent person would have acted under the same or similar circumstances.
